SPECIFICATION forming part of Letters Patent No. 584,154, dated June 8,1897. Applicaticn iilecl January 8, 1897. Serial No. 618,42 7. (Nomodell To all whom it' may concern..-

Be it known that I, CHARLES IV. DUNN, Sr., a citizen of the UnitedStates, residing at Quincy, Adams county, State of Illinois, haveinvented a certain new and useful Improvement in Hand-Bellows, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part of this specification.

My invention relates to an improvement in band-bellows, the improvementconsisting in a novel arrangement and construction of the head or mouthend of the bellows.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claim.

Figure I is a top view of my improved bellows. Fig. II is a side view, aportion of the lower part of the bellows being shown broken out insection to afford a view of the inletvalve. Fig. III illustrates alongitudinal section, taken on line III III, Fig. I, through the head ormouth end of the bellows. Fig. IV illustrates a cross-section taken online IV IV, Fig. I. Fig. V is a detail inner view of one of thebellows-boards, showing the flexible strips previous to attachment thatfold over the hinge at the mouth end of the bellows to incluse saidhinge. Fig. VI is a similar view to Fig. V, showing the flexible stripsfolded over the hinge and attached. Fig. VII is a longitudinal sectionof `the mouth end of the bellows, illustrating the employment ofopenings in both of the bellows-boards and aconducting-plate over eachof said openings and also illustrating in section the hinge and theiiexible strips located over said hinge.

In the drawings, l and 2 respectively designate the top and bottoniboards, joined by a liexible connection 3, as usual.

el designates the inlet-valve, and la and 2 the operating-handles on theboards l and The boards l and 2 are connected to the head end of thebellows by a leaf-hinge 5, located between them. In one of the boards lor 2 is au openin g (i, from which a channel G leads to the mouth of thebellows, as illustrated in Figs. III and IV, or there may be an openingin each board, as illustrated in Fig. VII.

Over the opening (i and channel 6, whether there be but one or both ofthe boards provided with such openings and channels, a conducting-plate7 is attached to the exterior of the board, being secured by screws S orother suitable means of fastening. Each conducting-plate 7 is providedwith a channel 9,

closed at the rear end and open at the outer end. The air enters thebellows through the inlet-valve 4, as in the ordinary form of bellows,and is on the compression of the bellows forced out through the opening6, the channel G, and the channel 9 in the conducting-plate 7. There twoopenings 6 and two conducting-plates are employed in and on the twoboards of the bellows, the blast of air through the channels of the twoboards are concentrated as they emerge at the mouth ends of the channels9.

In Fig. II, I have shown one conductingplate 7 in full lines and oneconducting-plate in dotted lines, thus illustrating the employm ent ofeither a single or double mouth outlet.

Over the hinge 5, by which the boards l and 2 are connected at theirhead ends, I attach a flexible cover l0, that incloses the outer edge ofthe hinge. Attached to the edges of the boards l and 2 are flexiblestrips ll, that are folded over the head ends of the boards and over thehinge 5 and its cover l0. These strips overlap each other, and theirends are brought around against the opposite edges of the boards fromJthat of their rst attachment and said en ds there attached. Thisarrangement eifectually incloses the hinged joint and hinge and preventsany leakage of air at such joint.

I cla-iin as my invention- In a hand-bellows, the combination of boardsflexibly connected, a hinge located between and connecting said boardsat the head 'or mouth end of the bellows, a covering for said hinge, andstrips attached to the edges of said boards', and extending over saidhinge and covering, substantially as described.
